NAlL-EXTRACTOR.

SPECIFICATION forming part of Letters Patent No. 243,812, dated July'5, 1881.

Application filed February 15, 1881.

To all whom it may concern:

Be it known that I, Fnnnnnrcx M. SrEvENs, of Waterbury, in the county of New Haven and State of Connecticut, have invented. an Improvement in Nail-Extractors, of which the following is a specification.

Nail-extractors have been made with a compound claw at the end of alever and a sliding rammer to apply percussive force to the jaws and drive them into the wood at each side of the nail-head. A nail-extractor of this character is shown in Letters Patent No. 143,496. In this patent the sliding tubular rammer is connected with the stem or lever of the nailj extractor by means of a strap passed over buttons on the stem and rammer respectively, and the said strap is liable to become broken or unbuttoned, and the rammer to get separated from the rest of the extractor.

My present improvement is made for connecting the rammer to the stem or lever of the nail-extractor in a simple and strong manner, and so that it is free to be moved endwise of the stem, but cannot be separated therefrom; and the shape of the rammer is such that the percussive force is applied in the most efl'ective manner to the stem of the nail-extractor.

In the drawings, Figure l is an elevation, partially in section, and Fig. 2 is asectional plan at the line 00 w.

The jaws a and e, pivoted at I), and the toepieoe d of the jaw e, are similar to those in the aforesaid patent; so, also, is the stem or lever E, except that a hole is made across it near the end for the reception of the pin or screw 8.

The percussive device or rammer is made of the tubular body t and its handle u. The

body t is cored out, so that the lower end is of a size to slide freely over the stem E, and

(No model.)

above this the hollow tubular portion is enlarged, leaving a shoulder, as at 20, against which the cross-pin or stop 8 may be arrested as the rammer is drawn back, so that the rammer and the other parts of the extractor cannot become separated, and when the rammer is projected downwardly, so as to strike against the end of the stem E, the ram mer slides freely on the stem. The heavier portion of the percussive device is around the stem, so that the shock is not felt materially upon the hand, and the greatest effect in proportion to the weight of the rammer is obtained.

In order to support the core that forms the enlarged tubular portion of the rammer, I make use of lateral openings m through the handle, which also are formed by core-prints. These openings allow for the introduction of the screw or rivet into the inner end of the stem.

I am aware that the hammer or percussive device in a nail-extractor has been provided with a screw-collar around the lever and a head upon the lever. These are expensive, and the screw-collar is liable to become detached.

I claim as my invention- The combination, with the nail-extracting jaws and stern, of sliding tubular rammer, having a shoulder at w and openings m, and the pin or screw 8 inserted in the stem, as specified.

Signed by me this 11th day of February, A. D. 1881.
